OIL-BURNER.

Application filed October 25, 1913.

To all whom it may concern Be it known that 1, LEE S. CHADwIcK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State-of Ohio, have invented a certain new and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to oil burners, and has for its object to provide such burners with means whereby the wick may be raised and lowered within predetermined limits and, more particularly, to provide the wick raiser with an indicator which is capable of showing at all times the exact height of the wick and which is provided with means whereby it may be adjusted, as occasion may require, to compensate for the consumption and cleaning of the wick.

Aanong the objects of the invention are the production of a device of this kind which shall have the capabilities of operation referred to hereinbefore; which shall be simple of construction and convenient of operation; and generally responsive to all requirements and incidents of use.

Further objects of the invention will appear hereinafter and may be defined generally as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings accompanying and forming part hereof, wherein- Figure 1 represents a view, partly in section and partly in elevation, of a burner having my invention applied thereto; Fig. 2 is an elevation, with parts broken away, of the burner and raiser shown in the preceding figure; Fig. 3 is a detail in section and elevation of the wick raiser and the associated parts; Fig. f a bottom plan view of a portion of the wick raiser; Fig. 5 a side elevation and Fig. 6' a sectional front elevation of a modified form of the invention.

Describing by reference characters the various parts shown herein, 1 denotes the inner and 2 the outer wick tube of a burner of any approved construction. Between these tubes there is shown a wick 3, the wick being provided with a carrier l, said carrier being formed of perforated sheet metal.

5 denotes the spindle of the wick raiser, said spindle being provided with a double starwheel 6, which engages the perfora Specification of Letters Patent.

tions of the wick carrier. The spindle 5 s provlded at its outer end with an operatng handle 6, rigid therewith, said operat- 111g handle being in the form of a hand wheel which may be conveniently formed of sheet metal having a flange or skirt 7 extending toward the lower end of the spin dle 5 and-being substantially.parallel with sa d spindle. The bottom of this flange or skirt 7 is provided with teeth or serrations 8, for a purpose to be described hereinafter. The spindle 5 is mounted within a sleeve 9, which extends through the housing 10. a supporting lug 11 and a plate 12, said lug and plate being soldered to the outer wick tube, the latter being provided with an extension 13 for facility of application to the said wick tube.

The plate 12, as will be more evident from Fig. l, is provided with a segmental scale 14 which is adapted to cotiperate with an indicating finger carried by and movable with the spindle 5. The scale 1-1 is provided with the word Clean at the central portion thereof, the word Out at one end thereof, and the word Up or Full may be provided at the opposite end; although a stop 15, which limits the rotation of the spindle in a wick-raising direction, enables the legend at this end of the scale to be dispensed with.

The indicating finger is conveniently and cheaply formed as one branch of a U-shaped sheet metal strap, the said strap being mounted on the sleeve 9 and the sleeve eX- tending through both branches thereof. The indicating finger, shown at 16, is provided with a pin 17 which projects toward the plate 12, and the other end 16 of this finger swings above the scale 1%. The other branch 18 of the U-shaped strap has its end bent upwardly, as shown at 19, and is provided there with serrations or teeth adapted to mesh with the serrations 8 on the operating handle (i A spring "20, surrounding the sleeve 9 and bearing against the plate 12 and the branch 16, normally maintains a driving connection between the spindle 5 and the indicating finger 16, through the engagement of the serrations 18 of the strap with the serrations on the hand wheel.

It will be noted that, in radial line with the center of the scale 14 and in line with the word Clean, the plate 12 is provided with a hole 12.

In Fig. 5 there is shown a modification of my invention wherein the finger 16 of the U-shaped strap is provided at its outer extremity with a stop lug 21, which is conveniently formed by bending the outer extremity of the finger substantially at right angles to the body thereof. This stop lug cooperates with a notch 2-2 in the curved periphery of the plate 12 as well as with the projection 15 As in the preceding embodiment of my invention, the driving connection between thespindle and the finger is secured by means of the spring 20 which normally holds the serrations in the flange 19 in engagementwith the serrations on the operating handle 6 With the parts constructed as described,

the operation will be as follows: The plates 12, 12 and the segmental scale thereon will be so arranged and proportioned with reference to the wick spindle that, when the I finger 16, 16 is at the center of the scale,

above the word Clean ,the top of the wick 0 will be substantially flush with the tops of the wick tubes. In this position, the Wick may be cleaned by rubbing the top thereof with a cloth or other suitable object. The parts will be so proportioned further that, when the pin 17, 21 is in engagement with the stop 15, 15*, the wick will be at full height and, in the form of burner shown herein, this fullheight will be with the Wick slightly below the spreader plate 23.

Asthe wick necessarily becomes shortened,

through its continued operation, some .means I for adjustment between the finger 16,16 and the wick spindle 15 must be provided. This adjustment is accomplished by rotating line with the hole 12*, 12 served that ordinarily the pin or projection (17, 21) is in such close proximity to the cooperating plate therebeneath that in sufficient room is provided to permit the disengagement of the U-shaped strap from the serrations in the hand wheel. This disengagement can be accomplished only when the pin or projection (17, 21) is above the corresponding hole 12, 22 in the plate, or when the finger has been moved entirely off the plate in the out direction. It will be observed further that no such adjustment can be made when the finger is at the full height position, since the pin or projection (17, 21) is engaged by the stop 15,15 2 Ordinarily, however, the adjustment will be effected only when the pin or projection is above the hole near the middle of the plate opposite the word Clean. When in this position, the operator can press downwardly upon the finger 16, 16, the pin or projection then passing throughthe hole 12 22, thereby disengaging the serrations in the flange 19 o from those in the hand wheel 6. The splnthe spindle until the pin 17, 21 comes in.

It will be obdle can then be rotated until the top of the wick is brought flush with the top of the wick tubes, whereupon the pressure upon the finger 16, 16 can be relieved and the indicating finger will again be locked to the wick spindle.

Among the advantages of this invention are the fact that the stop 15, 15"-, in conjunction with the indicating finger, provides means whereby it will be impossible to turn the wick too high, thereby securing proper functioning of the wick. Furthermore it will be apparent that a change of adjustment can be made only when the wick is turned to clean or extreme out position, with the top of the wick either substantially flush with the tops of the wick tubes or at a considerable distance below the tops of said tube. Still further, as will be plainly apparent, the construction is extremely simple and economical of production and is clearly efficient in operation.
